The present invention relates to a composite preparation with various dosage forms comprising mosapride and rabeprazole. The composite preparation prepared according to the present invention allows rapid release of a drug without deteriorating its release by an interaction between mosapride and rabeprazole, thus exhibiting an improved drug release rate and bioavailability, while having excellent product stability and being capable of significantly lowering the amount of the excipient. Accordingly, the composite preparation of the present invention can improve patients' drug compliance due to the size of its dosage form.

Composite preparation of mosapride and rabeprazole

The formulation for oral administration of the present invention containing Mosapride or its salt is a double layer formulation consisting of a fast-release layer for rapid release of a drug and a sustained-release layer for slow release in order to simultaneously satisfy the rapid exhibition of pharmacological activities and sustained maintenance of pharmacological activities for 24 hours, wherein the high-viscosity hydroxypropyl methylcellulose (HPMC) and the low-viscosity HPMC are used in mixture such that the content of a high viscosity HPMC as a controlled-release matrix within the sustained-release layer has a higher content, thereby capable of controlling the dissolution rate in the regions having different pH values within the gastrointestinal tract and/or the retention time in the gastrointestinal tract. Additionally, the formulation of the present invention is a small-sized preparation with a total weight of 200 mg or less, preferably from 150 mg to 160 mg, thus capable of improving drug compliance of patients.
